Aerosol Laser ƙididdiga Mai gano Nano Quantity Analyte
- Wide kewayon aikace-aikace: kusan duk non-volatile da kuma rabin volatile abubuwa za a iya ganowa
- Babban ƙwarewa: Ya kai matakin ng (1-2 matakan girma fiye da ELSD)
- Quality amsa irin: daidaito siginar amsa dogara ne kawai a kan inganci, ba tare da sinadarai
- Yanzu m amsa kewayon: m saka idanu kewayon har zuwa 4 girman matakan, daga ng zuwa µg
- Kyakkyawan kwanciyar hankali na muhalli: Kusan babu tasirin canje-canje na muhalli na waje kamar zafin jiki
- Tattalin arziki muhalli: Za a iya amfani da matsa iska kawai, kuma za a iya amfani da nitrogen
- Operation intuitive: Touch allon panel aiki
- Maintenance mai sauki: kawai sauya kayan aiki a kowane rabin shekara
- * Osaka Caoda Co., Ltd. ne ta samar da wannan na'urar
